It lets you re-encode MP3 files to a different bitrate in no time, which is great if you want to tidy up your music library or make songs ready for your phone or music player. Say you’ve got a bunch of 320 kbps tracks—you can shrink them down to 192 or even 128 kbps. You’ll save a lot of space and the audio will still sound pretty good.
